Answer:
(7, 0 )
Step-by-step explanation:
Given the 2 equations
y = - 2x + 14 → (1)
y = 2x - 14 → (2)
Since both equations express y in terms of x we can equate them
2x - 14 = - 2x + 14 ( add 2x to both sides )
4x - 14 = 14 ( add 14 to both sides )
4x = 28 ( divide both sides by 2 )
x = 7
Substitute x = 7 into (2) for corresponding value of y
y = (2 × 7) - 14 = 14 - 14 = 0
Solution is (7, 0 )
Answer:
Step-by-step explanation:
Looking at the right angle triangle that contains x and y, we would apply trigonometric ratio to determine x an y. Taking 60 degrees as the reference angle,
Hypotenuse = y
Adjacent side = x
Opposite side = 36
Therefore,
Sin # = opposite side / hypotenuse
Sin 60 = 36/y
y = 36/Sin60 = 36/0.8660 = 41.57
Cos # = adjacent side/hypotenuse
Cos 60 = x/41.57
x = 41.57Cos 60 = 41.57 × 0.5 = 20.785
Sin45 = z/36
z = 36Sin45 = 36 × 0.7071 = 25.4556
Answer:
10
Step-by-step explanation:
f(x) = 3x + 1
f(3)= 3 * 3 + 1 + 10
Answer:the mean is 90
Step-by-step
you find the sum of the values then divide them by the amount of numbers in the set
Answer: Mrs.Buller collects a 500-ml sample of seawater for her chemistry class, and it has 1.94% of chlorine, we have to determine the amount of chlorine in the sample:
Therefore the chlorine content in 500ml of water is 9.7ml.
